Outdated info here, but to give you an idea, looking at the packet presented to me in early 2014:

Employee + Family

• $286.30 / month - Value High Deductible Health Plan

• $416.38 / month - Traditional PPO

• $653.02 / month - Legacy PPO

For family Dental add another $60 or $100 / month for standard or premium.

These premiums went up for 2015, but I'm not sure by how much. I'll find out in the coming weeks as I'll be transitioning over to one of them.
